I currently have two OMV servers but may have a couple more in the future. I have a CP1000PFCLCD ups. From what I have read, each UPS connects to the server via USB and when the server sees that its on battery it will issue a shutdown command. Is there any want to use a single UPS for multiple servers? USB hub or something?
My one thought is a script to run on server B to ping server A and if it does not get a response then to shutdown.
